Description
Technical field
The present invention relates to a kind of optical-fiber coupling connector and manufacture method thereof.
Background technology
Along with the development of high in the clouds technology, the following high speed transmission system that can need more and more higher frequency range.At present the IBM mode of being devoted to the development utilization planar optical waveguide replaces traditional copper cash framework, utilizes the light transmission to interrogate at a high speed, replaces passingly to pass high speed signal by fax.
The planar optical waveguide framework that proposes at present is that laser diode or light emitting diode, photoelectric detector and respective drive is circuit integrated at a LTCC(low temperature co-fired ceramic, low-temperature co-fired ceramic substrate) on, need on LTCC, through hole be set so that the optical window of laser diode or light emitting diode and photoelectric detector is aimed at LTCC, light is changed into the light of vertical direction by a reflector element light of horizontal direction after passing LTCC, then is coupled into planar optical waveguide to grow Distance Transmission.
Due to laser diode or light emitting diode, photoelectric detector and respective drive circuit volume smaller, therefore the precision requirement of through hole is very high, will be very little except the aperture, also need simultaneously very high precision, thereby make the cost of optical-fiber coupling connector higher.
Summary of the invention
In view of this, be necessary to provide optical-fiber coupling connector and the manufacture method thereof that a kind of cost is lower, yield is higher.
a kind of optical-fiber coupling connector, comprise photovoltaic element, planar optical waveguide, ceramic substrate substrate and circuit board, described photovoltaic element has light-emitting area and sensitive surface, described ceramic substrate has relative first surface and second surface, described circuit board has the 3rd relative surface and the 4th surface, described photovoltaic element electrically be arranged on the second surface of described ceramic substrate by the COB processing procedure and described light-emitting area and sensitive surface towards the 3rd surface of described circuit board, described planar optical waveguide is positioned on the 3rd surface of described circuit board, be provided with reflector element between described ceramic substrate and described circuit board, the light that the light-emitting area of described photovoltaic element is sent is coupled into described planar optical waveguide after described reflector element reflection, the light of described planar optical waveguide outgoing is received by the sensitive surface of described photovoltaic element after described reflector element reflection.
A kind of manufacture method of optical-fiber coupling connector, described optical-fiber coupling connector comprises photovoltaic element, ceramic substrate and circuit board, have planar optical waveguide on described circuit board, the manufacture method of described optical-fiber coupling connector comprises the steps: to adopt the COB processing procedure to be arranged on the surface of described ceramic substrate described photovoltaic element; On described ceramic substrate, ball grid array is set; Overturn described ceramic substrate so that the planar optical waveguide of described photovoltaic element on described circuit board; Connect described ceramic substrate and circuit board by ball grid array.
Compared to prior art, the photovoltaic element of the optical-fiber coupling connector of the present embodiment adopts the COB processing procedure to be arranged on substrate and light-emitting area and sensitive surface all towards circuit board, do not need to arrange the higher through hole of precision on substrate thereby make, can realize the optically-coupled between photovoltaic element and planar optical waveguide, therefore, the cost of optical-fiber coupling connector is lower, is arranged on substrate because photovoltaic element adopts the COB processing procedure again, thereby makes the yield of optical-fiber coupling connector higher.

Embodiment
See also Fig. 1, the optical-fiber coupling connector 100 that the embodiment of the present invention provides comprises ceramic substrate 10, circuit board 20, planar optical waveguide 30, reflector element 40 and lens 50.
Planar optical waveguide 30 is arranged on the 3rd surface 21 of circuit board 20 and is used for being coupled to realize Propagation of light rays with photovoltaic element 13.
In optical-fiber coupling connector 100 transmitting optical signal processes, the light emitting diode 130 that chip 131 drives photovoltaic element 13 sends the light of basic vertical ceramic substrate 10, light incides on lens 50, become the light of substantially parallel circuit board 20 from the light of lens 50 outgoing after reflector element 40 reflections, the light of substantially parallel circuit board 20 enters planar optical waveguide 30 transmission.In like manner, incide on lens 50 after reflector element 40 reflections from the light signal of planar optical waveguide 30 outgoing, received and be converted to electric signal from the light of lens outgoing by photodiode, chip 131 is processed the signal that electric signal is transmitted to obtain optical-fiber coupling connector 100.
In manufacture process, adopt the COB processing procedure to be arranged on the second surface 12 of ceramic substrate 10 photovoltaic element 13, then ball grid array 60 is set on ceramic substrate 10, upset ceramic substrate 10 is so that the planar optical waveguide 30 of photovoltaic element 13 on circuit board 20 connects ceramic substrate 10 and circuit board 20 by ball grid array 60.
The light-emitting area of the photovoltaic element 13 of optical-fiber coupling connector 100 and sensitive surface are all towards circuit board 20, the higher through hole of precision need to be set on ceramic substrate 10, can make photovoltaic element 13 and planar optical waveguide 30 realize optically-coupled, thereby make the cost of optical-fiber coupling connector 100 lower; Be arranged on ceramic substrate 10 because photovoltaic element 13 adopts the COB processing procedure again, thereby make the yield of optical-fiber coupling connector 100 higher.
